Anti-ICE rioters attacked Los Angeles police officers while attempting to break into a federal courthouse on Friday, prompting Los Angeles Mayor Karen Bass to warn that disorder could cause the military to be deployed to the city.

“A Dispersal Order was issued and as Officers began to move the line, agitators in the coward began to throw water bottles and other objects at the officers resulting in less than lethal munitions being deployed,” the LAPD reported. “Arrests have been made.”
